Objective:  The purpose of this study was to clinically evaluate Finesse all ceramic restorations (Ceramco, Inc.) when used in conjunction with a new esthetic resin cement.

Methods:  Forty posterior and anterior crowns, twenty all ceramic inlays and onlays, and twenty-six veneers were placed in forty-three patients.  Standard ceramic preparations were performed followed by conventional polyvinylsiloxane impression techniques using cord retraction.  Calibra (L.D. Caulk) resin luting agent was used to cement the restorations following manufacturer's instructions. 

Results:  The restorations were evaluated at baseline (B), 6 months (6M), 12 months (12M), and 24 months (24M) using modified Ryge criteria shown as Alfa percentages:

Alfa Percentages
	Crowns					Inlays/Onlays					Veneers
	B	6M	12M	24M		B	6M	12M	24M		B	6M	12M	24M
Color Match	95	97	97	97		100	100	100	100		100	100	100	100
Marginal Adapt.	98	100	100	100		100	100	90	88		100	100	100	100
Porcelain Staining	100	100	100	100		100	100	100	94		100	100	100	100
Retention Rate	100	100	100	100		100	100	100	94		100	100	100	100
Secondary Caries	100	100	100	100		100	100	100	100		100	100	100	100
Post-Op Sensitivity	98	97	97	97		95	94	90	94		100	100	100	100
Recall Rate	100	97	97	95		100	95	100	84		100	100	100	100

 

Conclusion:  The data supports that there were sufficient shades available to obtain desired esthetic result with 99% of all restorations being rated Alfa for shade match to Vita (Vident) shade guide.  Additionally, there were no bulk ceramic fractures.  All restorations evaluated were clinically acceptable after 24 months.  This study was supported by Ceramco, Inc.
